i purchased 4 coturnix quail on saturday november 3,they were 3 weeks old when i got them(i got 1 rooster and 3 hens). this afternoon i went to their pen to check on them, then i saw an egg. then i saw 2 more, so i got three eggs and there are three hens so i guess they each laid an egg.The thing that confuses me is that they are only 5 weeks old and they are already laying!!! but what i really need to know is are the first eggs going to be fertile? and do they really need nesting boxes? also how long and what temperatures and humidity will the incubating process need????
